I think something like
/sys/class/misc/debug/panic_notifier/ipmi/priority /sys/class/misc/debug/panic_notifier/watchdog/priority /sys/class/misc/debug/panic_notifier/kdb/priority /sys/class/misc/debug/panic_notifier/kdump/priority
would be better. It's more self-describing if you want to change the order.
Thanks, Bernhard
